NEON Biorepository Terrestrial Plant Collection (Herbarium Vouchers)

This collection contains terrestrial plant vouchers collected from select species during plant diversity sampling (NEON sample class: div_voucher_in.voucherSampleID.pla). Plant species diversity is measured once or twice annually in the field. The plot-based method yields plant species data at multiple scales that provide an understanding of changes in composition, distribution, and abundance of native and non-native plant species. The data is comparable within and across NEON sites and to other continental plant diversity efforts to allow for a comprehensive understanding of the impacts of the drivers of change on the diversity of plant species and the functional role they play in ecological systems. A subset of observed plant species is collected and archived. These vouchers are housed at NEON facilities for reference and archived in the NEON Biorepository's herbarium.
